Patented Mar. 9, 1937 UNITED STATES FATENT OFFICE 2,073,043 BOTTLESTOPPER Wilhelm Albrecht, New York, N. Y. Application February 26, 1935,Serial No. 8,244 2 Claims. (01. .215- "vs) My invention relates to animprovement in bottle stoppers. The primary object of the invention isto provide a removable stopper to fit within the neck of a bottle, whichincludes, in association therewith, a counterbalanced closure, or capfor the bottle, which automatically covers the stopper when the bottleis in an upright vertical position. The closure, or cap, functionsautomatically to uncover the bottle stopper when the bottle is tiltedinto a position to pour out the contents of the same.

A further object of the invention is to provide an extending tubularmember positioned with the stopper facilitating the withdrawal of theliquid contents of the bottle in such a manner aS to prevent the samefrom passing over the top surface of the stopper.

Another object of the invention is to construct a stopper to permit theremoval of the automatically operating cover attachment therefrom.

My invention further includes other objects and advantages hereinaftermore particularly referred to in connection with the detaileddescription of the same with the accompanying drawing, which 25 show theinvention in its preferred physical embodiment.

Referring to the drawing:

Fig. 1 is a perspective view of the bottle stopper constructed inaccordance with the present in- 30 ventive conception illustrating thesame mounted on a bottle, which is in a tilting or pouring position.

Fig. 2 is a side elevation of the bottle stopper attachment indicatingthe cover of the same in 35 a closed position.

Fig. 3 is a detailed perspective view of the connecting member employedfor pivotally retaining the counterbalanced cover member of the stopperthereon.

Fig. 4 is a similar view of the bottle stopper with the cover attachmentremoved therefrom.

Fig. 5 is a detailed perspective view. of the member employed forpositioning the stopper within the neck of the bottle.

Fig. 6 is a detailed plan view of the cover attachment, and

Fig. '7 is a detailed perspective view of the extending tubular memberpermitting the passage of the contents of the bottle through thestopper. 50 The bottle stopper, as herein disclosed, comprises atapering retainer member ID, indicated in detail in Fig. 5, formed ofcork, or a similar compressible material, which is removably locatedwithin the neck of a bottle I l. The taper- 55 ing retainer 19 includesa central longitudinal opening [2, through which a tube l3 extends, thetube being held firmly in position therein by the circumferentialinterior surface defining the opening in the retainer. An interiorlythreaded outer portion or band 14 is positioned about the upperperipheral surface of the cork retainer. The band includes externalupper and lower flanges 45 and I6 respectively. A plurality ofprojecting lugs H are located in the surface of the band situatedbetween the limiting flanges l5 and IS. The associated relationship ofthe cork retainer member It}, band I4 and tube I3 is clearly illustratedin Fig. 4 of the drawing, which shows an assembly view of these elementsof the invention. The portion of the retaining member 19 below the bandI4 is employed to securely hold the connected parts within the neck of abottle as indicated at l8 in Fig. 2. The tubular member provides apassageway for the contents of the bottle to flow through the stopper,this tube extending above the upper or top surface of the stopper asdefined by the flange 15 and cork H) in order to prevent a flow ofliquid over this portion of the device, when the bottle is tilted forthis purpose. The portion of the stopper projecting above the top of theneck of the bottle provides a retaining means for positioning anautomatically operative cover attachment thereto, as will hereinafter bemore particularly described.

With particular reference to Figs. 3 and 6 of the drawing, the removablestopper cover attachment herein disclosed comprises a circular band l8having raised parallel arms l9 extending therefrom. This spacing memberof the attachment is also provided with indentations 20, and when placedin position between the spaced circumferential flanges l5 and I6 andaround the band M of the stopper, the same mesh with the projections Hand prevent the adjoining parts from moving with relation to one anotherin assembled relationship. By spreading the arms IQ of the circular band18', the same may be removed from a position about the periphery of thestopper band 14. Adjacent openings in the end portions of the respectiveextending arms of the spacing member, as indicated at 2|, are adapted topivotally maintain side lugs 22 on the body of a cover member 23, Fig.6. One end of the cover member 23 is of a closed top cylindrical shape,as indicated at 24, having an interior washer 25 of cork, or similarmaterial, which closes the extending tube l3 when the bottle containingthe stopper is in a vertical position, as shown in Fig. 2. Acounterweight 26 is located at the opposite end of the cover member 23,counterbalancing the weight of the cylindrically shaped closing portionof the cover, so that, when the bottle is tilted to pour the contentstherefrom, the closing portion 24 will automatically uncover the mouthof the tube l3, as indicated in Fig. 1. Lugs 21 are provided on thecover member to limit the degree of movement between the pivotallyconnected parts of the bottle stopper attachment.

While I have shown and described the preferred embodiment of myinvention, I do not desire to limit myself to the specific formillustrated, but may alter the construction and arrangement of parts, asoccasion requires, without enlarging the scope of my invention, ordeparting from the spirit thereof, as contained in the appended claims.

I claim:

1. A bottle stopper, having an upper portion projecting above the neckof the bottle in which it is adapted to be secured, said portionincluding a band having upper and lower flanges, a spacing connectionfastened about said band between the fianges thereof, and acounterweight cover attachment pivotally mounted in said spacingconnection for closing the top of the stopper when the bottle is in avertical position.

2. A bottle stopper having an outer portion comprising an integral bandhaving upper and lower external flanges, a spacing connection securedbetween the flanges of said outer portion, a counterweight coverattachment pivotally mounted on the spacing connection for closing thetop of the bottle stopper, and means for securing the stopper upon theneck of the bottle.
